BROKEN CROSSARM ON 'R' IN TRUST 1878-S SHORT NOCK--RARE OR COMMON?

[M W JOYNER]

Dear Friends,
I have an odd (or really common?) coin that I need help with VAMming.
1878-S Short Nock
Broken 'R' in 'Trust'....kind where the crossbar is totally gone.
2. The VAM 2 listing says "if you have found a 78-S short nock with fully broken crossarm, post on boards because this coin "likely" does not exist".
3. So, I am listing it here for help.
4. I also attached photos of obv/rev.
5. If this coin is "non-existing" why is it a mere R2 in rarity?
6. IF THIS SPECIMEN IS NOT THE VAM 2, WHICH VAM DOES IT REALLY BE?
Thank you friends for all of your assistance in answering my questions...preemptively.

There are many 78-S VAMs with the broken r. Can you get any better
close ups of the coin?

The most common 78-S with no crossbar r of trust is V-19A and V-74.
